It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0066] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0067] like Figure 1 As shown, the refrigerator is embedded in the wall 3, for example, zero embedding or flush embedding can be used. Zero embedding means that the refrigerator door 2 is flush with the wall, and flush embedding means that the door 2 extends beyond the wall, but the box body 1 is flush with the wall.

[0068] Figure 1The refrigerator shown includes a housing 1, which houses a refrigerator and a freezer. The freezer is located below the refrigerator. Both the refrigerator and freezer have double doors. The refrigerator has two doors 2 that can be opened outward from the center, and the freezer has two doors 2 that can be opened outward from the center. A support adjustment bracket 8 can be provided at the bottom of the housing 1 for adjusting the height of the housing 1. Each door 2 is provided with a connecting member 10 at both ends along the third direction z to enable rotation relative to the housing 1. That is, each door is provided with a connecting member 10 at both the top and bottom ends, and the connecting member 10 is located in the area near the outside of the door 2 along the first direction x.

[0069] In an optional embodiment, the refrigerator's refrigeration compartment or freezer compartment may also be provided with only one door body 2, or the refrigerator may only have a refrigeration compartment or a freezer compartment.

[0070] refer to Figure 2 In some embodiments, the refrigerator includes a cabinet 1 and a door 2. The cabinet 1 is provided with a take-out opening and a first connecting member 4. The door 2 is rotatably connected to the cabinet 1 to open or close the take-out opening. The door 2 is provided with a second connecting member 5.

[0071] Among them, one of the first connecting member 4 and the second connecting member 5 is provided with a first hinge shaft 41 and a second hinge shaft 42, and the other of the first connecting member 4 and the second connecting member 5 is provided with a first groove 51 and a second groove 52, the first hinge shaft 41 is arranged in the first groove 51, and the second hinge shaft 42 is arranged in the second groove 52.

[0072] When the door body 2 is in the closed state, the first groove 51 extends along the side extension surface N close to the box body 1, and first approaches the box body 1 and then extends away from the box body 1; the second groove 52 extends along the side extension surface N close to the box body 1 and the direction of the box body 1.

[0073] Items can be placed in or taken out of the box body 1 through the access opening. The connecting component 10 includes a first connecting member 4 and a second connecting member 5 that cooperate with each other. There are two hinge shafts between the door body 2 and the box body 1, including a first hinge shaft 41 and a second hinge shaft 42. The first groove 51 limits the first hinge shaft 41, and the second groove 52 limits the second hinge shaft 42. During the opening or closing process of the door body 2, the first hinge shaft 41 moves along the first groove 51, and the second hinge shaft 42 moves along the second groove 52. The virtual rotation axis of the door body 2 is not fixed and moves inward along the first direction x during the opening process of the door body 2.

[0074] The door 2 has a side wall 21, which is located on the side closest to the connecting member 10 along the first direction x. When the door 2 is closed, the side wall 21 can coincide with the side extension surface N. When the door 2 is opened, the side wall 21 moves slightly inward. The side of the side wall 21 away from the box body 1 has a first ridgeline L1, and the side of the side wall 21 close to the box body 1 has a second ridgeline L2.

[0075] like Figure 9 As shown, when the door body 2 is in the closed state, the first groove 51 extends along the side extension surface N close to the box body 1, and first approaches the box body 1 and then extends away from the box body 1; the second groove 52 extends along the side extension surface N close to the box body 1 and the direction of the box body 1.

[0076] When the door body 2 is in the closed state, the extension trajectory of the first groove 51 and the second groove 52 can be straight or curved, as long as the overall position change trend mentioned above is followed. In addition, "approaching" not only includes approaching along the entire extension length, but also can include the end being closer to the box body 1 or the side extension surface N than the beginning, but there is a partial distance between the trajectory and the distance remaining unchanged. For example, the second groove 52 extends in a direction close to the box body 1, and can gradually approach the box body 1 in the first movement stage, and maintain a constant distance from the box body 1 in the second movement stage.

[0077] In this embodiment, when the door 2 is opened, the two hinge shafts are movable relative to the slots in which they are located. The position of the rotation axis of the door 2 can be changed in real time according to the opening and closing angle of the door 2, so that the movement trajectories of the first edge line L1 and the second edge line L2 are both located inside the side extension surface N of the cabinet 1. Therefore, when the refrigerator is embedded in the wall, the reserved space on the side of the cabinet 1 along the first direction x can be reduced, so that the door 2 can be opened better without touching the wall 3. The door 2 can be smoothly opened to 90° or more, which can save installation space and provide convenience for users.

[0078] In some embodiments, the first groove 51 and the second groove 52 each include an arc segment and two straight segments, with an angle between the two straight segments, and the arc segment smoothly connecting the two straight segments. The angle can be acute, right, or obtuse. The angle is toward the side away from the box body 1.

[0079] In this embodiment, by connecting the two straight segments with an arcuate segment, the hinge axis can smoothly cross the turning point when moving to the connection between the two straight segments, preventing the occurrence of a dead point, thereby making the rotation of the door body 2 more flexible and smooth. Moreover, most of the paths of the first hinge axis 41 and the second hinge axis 42 are straight lines. If the positions of the two hinge axes relative to the slot change, it is easier to accurately ensure the distance between the two hinge axes during design and processing, thereby improving the flexibility of the rotation of the door body 2.

[0080] In some embodiments, as Figure 9 As shown, when the door body 2 is in the closed state, the first slot 51 is located on the side away from the box body 1 relative to the second slot 52. In the second direction y, the second slot 52 can be entirely located between the first slot 51 and the box body 1, or at least part of the length of the second slot 52 is located between the first slot 51 and the box body 1.

[0081] In some embodiments, the extension length of the first slot 51 is shorter than the extension length of the second slot 52. Since the first hinge shaft 41 is closer to the rotation axis of the door body 2 during opening, a shorter extension length for the first slot 51 can reduce the distance the door body 2 moves inward during opening. This can reduce the distance between the two doors 2 when using a double door. The second hinge shaft 42, on the other hand, is farther from the rotation axis of the door body 2 and requires a longer extension length to accommodate the movement trajectory of the door body 2.

[0082] In some embodiments, the first slot 51 and the second slot 52 are entirely located in the area corresponding to the door body 2. Accordingly, the first hinge axis 41 and the second hinge axis 42 are also located in the corresponding areas of the door body 2. This embodiment facilitates using the entire extension length of the first slot 51 and the second slot 52 as the effective limiting length, allowing the hinge axis to be accurately limited by the starting and ending points of the slots.

[0083] In some embodiments, as Figure 8 As shown, the first slot 51 includes a first straight segment 511, a first arc segment 512, and a second straight segment 513, which are connected in sequence. The first straight segment 511 and the second straight segment 513 form a first angle between them, and the opening of the first angle faces away from the housing 1. As can be seen from the figure, the first angle is close to a right angle, and the lengths of the first straight segment 511 and the second straight segment 513 are similar. For example, the first arc segment 512 can be a circular arc segment.

[0084] In some embodiments, as Figure 8 As shown, when the door body 2 is in a closed state, the first hinge shaft 41 is located at the first starting end A1 of the first straight segment 511 away from the first arc segment 512, and the first hinge shaft 41 moves in sequence along the first straight segment 511, the first arc segment 512 and the second straight segment 513 during the opening process of the door body 2.

[0085] Specifically, the first slot 51 has a first starting end A1, a first midpoint A2 of the A track, a second midpoint A3 of the A track, a third midpoint A4 of the A track, a fourth midpoint A5 of the A track, and a first end A6. The first midpoint A2 of the A track is the connection point between the first straight line segment 511 and the first arc segment 512, the second midpoint A3 of the A track is the connection point between the second straight line segment 513 and the first arc segment 512, the third midpoint A4 of the A track and the fourth midpoint A5 of the A track are located between the second midpoint A3 of the A track and the first end A6, and the third midpoint A4 of the A track is located between the second midpoint A3 of the A track and the fourth midpoint A5 of the A track.

[0086] In some embodiments, as Figure 8 As shown, when the door body 2 is in the closed state, the first straight line segment 511 extends from the first starting end A1 toward the direction close to the box body 1 and its side extension surface N; and / or the second straight line segment 513 extends from the second midpoint A3 of the A trajectory where it is connected to the first arc segment 512 toward the side extension surface N close to the box body 1 and away from the box body 1.

[0087] In some embodiments, as Figure 8 As shown, the second slot 52 includes a third straight segment 521, a second arc segment 522 and a fourth straight segment 523 connected in sequence, a second angle is formed between the third straight segment 521 and the fourth straight segment 523, and the opening of the second angle faces away from the box body 1.

[0088] As can be seen from the figure, the second angle is an obtuse angle, and the length of the third straight segment 521 is much longer than the fourth straight segment 523. Optionally, the length of the fourth straight segment 523 is shorter than the lengths of the first straight segment 511 and the second straight segment 513. For example, the second arc segment 522 can be a circular arc segment.

[0089] In some embodiments, when the door body 2 is in a closed state, the second hinge shaft 42 is located at the second starting end B1 of the third straight segment 521 away from the second arc segment 522, and the second hinge shaft 42 moves in sequence along the third straight segment 521, the second arc segment 522 and the fourth straight segment 523 during the opening process of the door body 2.

[0090] Specifically, second slot 52 has a second starting end B1, a first midpoint B2 of the B track, a second midpoint B3 of the B track, a third midpoint B4 of the B track, a fourth midpoint B5 of the B track, and a second end B6. First midpoint B2, second midpoint B3, and third midpoint B4 of the B track are located sequentially on third straight line segment 521 from second starting end B1. Fourth midpoint B5 of the B track is located at the largest corner of second arc segment 522.

[0091] In some embodiments, when the door 2 is closed, the third straight line segment 521 extends from the second starting end B1 toward the housing 1 and its side extension surface N; and / or the fourth straight line segment 523 extends from the connection point with the second arcuate segment 522 toward the side extension surface N of the housing 1, with the distance from the housing 1 remaining constant or being arranged at an angle. When the distance from the housing 1 remains constant, the fourth straight line segment 523 extends along the second direction y.

[0092] In some embodiments, as Figure 8 As shown, the first slot 51 includes a first straight segment 511, a first arc segment 512, and a second straight segment 513 connected in sequence. The first straight segment 511 and the second straight segment 513 form a first angle between them, and the opening of the first angle faces away from the housing 1. The second slot 52 includes a third straight segment 521, a second arc segment 522, and a fourth straight segment 523 connected in sequence. The third straight segment 521 and the fourth straight segment 523 form a second angle between them, and the opening of the second angle faces away from the housing 1.

[0093] The second straight line segment 513 is perpendicular to the third straight line segment 521, and the extension of the second straight line segment 513 intersects the third straight line segment 521 to form a third midpoint B4 of the B track. The third midpoint B4 of the B track can be located in an area of ​​the third straight line segment 521 near the second arc segment 522. For example, its distance from the second arc segment 522 can be 1 / 4 to 1 / 3 of the total length of the third straight line segment 521.

[0094] This embodiment can use the third middle point B4 of track B as the dividing position. In the process of the second hinge shaft 42 moving from the second starting end B1 to the third middle point B4 of track B, the first hinge shaft 41 mainly serves as the rotation center. During the movement, the first hinge shaft 41 will be subjected to the force exerted by the first groove 51, thereby driving the second hinge shaft 42 to move along the third straight line segment 521; when the second hinge shaft 42 reaches the third middle point B4 of track B and within a short distance beyond this point, the first hinge shaft 41 rotates at the first starting end A1, and then the rotation center is transformed into the second hinge shaft 42. During the movement, the second hinge shaft 42 will be subjected to the force exerted by the second groove 52, thereby driving the first hinge shaft 41 from rotation to movement along the second straight line segment 513.

[0095] like Figure 9 As shown, when the door body 2 is in the closed state, the first hinge shaft 41 is located at the first starting end A1 of the first slot 51 , and the second hinge shaft 42 is located at the second starting end B1 of the second slot 52 .

[0096] Door body 2 continues to open, as Figure 8As shown, when the first hinge axis 41 reaches the first middle point A2 of the A track where the first straight segment 511 and the first arc segment 512 are connected, the second hinge axis 42 is located at the first middle point B2 of the B track on the third straight segment 521 close to the second starting end B1.

[0097] like Figure 13 As shown, when the second hinge axis 42 reaches the third intermediate point B4 of the B track, the first hinge axis 41 reaches the second straight segment 513 away from the first end A6 of the first arc segment 512. At this time, the distance from the third intermediate point B4 of the B track to the first straight segment 511 is the shortest.

[0098] In some embodiments, when the first hinge axis 41 reaches the second midpoint A3 of the A track at the junction of the second straight segment 513 and the first arc segment 512, the second hinge axis 42 is located on the third straight segment 521, but not yet at the third midpoint B4 of the B track, and is close to the second midpoint B3 of the B track. Optionally, the distance between B3 and B4 is close to the distance between B1 and B2.

[0099] In some embodiments, as Figure 14 As shown, when the second hinge axis 42 reaches the fourth intermediate point B5 of the B track at the maximum corner of the first arc segment 512, the first hinge axis 41 reaches the third intermediate point A4 of the A track on the second straight line segment 513, and the third intermediate point A4 of the A track is close to the second intermediate point A3 of the A track at the connection between the second straight line segment 513 and the first arc segment 512.

[0100] like Figure 15 As shown, when the second hinge shaft 42 reaches the second end B6 of the fourth straight segment 523 , the first hinge shaft 41 reaches the fourth middle point A5 of the A track on the second straight segment 513 close to the first end A6 .

[0101] In some embodiments, the first straight segment 511 and the third straight segment 521 are arranged in parallel. This arrangement can make the door 2 open more smoothly.

[0102] In some embodiments, as Figure 6 As shown, the first connecting member 4 includes a first plate 44 and a second plate 45 connected to each other, the first plate 44 is connected to the box body 1, and the second plate 45 at least partially covers the door body 2 in the thickness direction, and the surface of the second plate 45 facing the door body 2 is provided with a first hinge axis 41 and a second hinge axis 42, or is provided with a first groove 51 and a second groove 52.

[0103] Among them, Figures 1 to 4As shown, the first plate 44 and the second plate 45 are connected to form an integral plate-like structure. A first hole 43 may be provided on the first plate 44, and a second hole 111 may be provided on the box body 1. The first fastener 6 passes through the first hole 43 and the second hole 111 to removably secure the first connector 4 to the box body 1. For example, two, three, or more first holes 43 may be provided. In order to ensure that the first connector 4 covers the second connector 5, for example, for the connecting component 10 provided at the top of the box body 1, the first connector 4 is located above the second connector 5. A raised portion 11 surrounding the first plate 44 may be provided on the wall surface of the box body 1. The raised portion 11 surrounds the outer periphery of the first plate 44 and may be flush with the surface of the first plate 44.

[0104] like Figure 6 As shown, the surface of the second plate 45 facing the door body 2 is provided with a first hinge shaft 41 and a second hinge shaft 42. When the door body 2 is in a closed state, the first hinge shaft 41 and the second hinge shaft 42 are spaced apart along the first direction x.

[0105] In some embodiments, a groove 22 is provided on the end surface of the door body 2, the second connecting member 5 is provided in the groove 22 and is covered by the first connecting member 4, and the second connecting member 5 is provided with a first groove 51 and a second groove 52 on the surface facing the first connecting member 4, or with a first hinge axis 41 and a second hinge axis 42. There is a height difference between the first connecting member 4 and the second connecting member 5.

[0106] Optionally, a third hole 53 may be provided on the second connecting member 5, and a fourth hole may be provided on the end face of the door body 2. The second fastener 7 passes through the third hole 53 and the fourth hole, and the second connecting member 5 may be detachably fixed to the box body 1. For example, the third hole 53 may be provided on the side of the second groove 52 away from the first groove 51.

[0107] like Figure 7 As shown, a first groove 51 and a second groove 52 are provided on the surface of the second connecting member 5 facing the first connecting member 4 .

[0108] This embodiment provides a groove 22 so that the second connecting member 5 can be embedded in the door body 2. For example, the outer surface of the second connecting member 5 is flush with the door body 2, so that the second connecting member 5 does not protrude from the door body 2, thereby ensuring consistency in appearance and minimizing the space occupied by the connecting component 10 in the third direction z.

[0109] During assembly, the first hinge shaft 41 and the second hinge shaft 42 on the first connecting member 4 are respectively inserted into the first groove 51 and the second groove 52 of the second connecting member 5. When the door body 2 is opened or closed, the first connecting member 4 is fixed and the second connecting member 5 rotates with the door body 2, ensuring that the first hinge shaft 41 always slides along the first groove 51 and the second hinge shaft 42 always slides along the second groove 52.

[0110] Since the door body 2 needs to be fixed with embedded hinge-type connecting components 10 at the top and bottom of the door body 2 when it rotates, Figure 2 As shown, the door body 2 and the box body 1 are modularly designed and replaced with a rectangular frame. The first connecting member 4 is secured to the box body 1 using a first fastener 6, and the second connecting member 5 is secured to the door body 2 using a second fastener 7. When the door body 2 opens and closes, sliding friction causes the door body 2 to rotate about the first hinge axis 41 and the second hinge axis 42.

[0111] The embedded hinge of the present application is an improvement on the traditional hinge, which improves the traditional single-axis hinge to a dual-axis rotation, and both axes are not fixed. When the door body 2 rotates, the track on the door hinge can roll around the two axes on the box hinge. When the traditional hinge mechanism is used to open and close the door, the axis of the hinge is fixed. However, due to the influence of the thickness and length of the door body, when the door body rotates around the center axis of the hinge, it is inevitable that a certain part of the door body will extend beyond the side of the box. Therefore, an improvement is made on this basis, and the axis of the fixed hinge is designed to be non-fixed, so that the two axes can move irregularly when the door body is opened and closed.

[0112] The following describes the movement of the first hinge shaft 41 and the second hinge shaft 42 during the process of the door body 2 from closing to opening. For the convenience of analysis, the first hinge shaft 41 is regarded as a mass point A, and the second hinge shaft 42 is regarded as a mass point B.

[0113] To facilitate understanding of the hinge motion trajectory, the second connecting member 5 is considered to be fixed and the first connecting member 4 is considered to be moving in the following description.

[0114] like Figure 9 As shown, initially the door body 2 is in a closed state, at which point the first hinge shaft 41 is located at the first starting end A1 and the second hinge shaft 42 is located at the second starting end B1. The first starting end A1 and the second starting end B1 are initial positions. When the user opens the door, a force is applied to the door body 2 at point C. At this time, the first hinge shaft 41 and the second hinge shaft 42 begin to move under the action of the force. After rotating a small angle, such as the first angle, Figure 10 As shown, the first hinge shaft 41 moves along the first straight line segment 511, and the second hinge shaft 42 moves along the third straight line segment 521. The door body 2 continues to rotate to the second angle, as shown in FIG. Figure 11 As shown, the first hinge shaft 41 moves to the first intermediate point A2 of track A, and the second hinge shaft 42 moves to the first intermediate point B2 of track B. The door body 2 continues to rotate to the third angle, as shown in FIG. Figure 12 As shown, the first hinge shaft 41 moves to the second middle point A3 of track A, and the second hinge shaft 42 moves to the second middle point B3 of track B. The door body 2 continues to rotate to the fourth angle, as shown in FIG. Figure 13As shown, the first hinge shaft 41 moves to the first end A6, and the second hinge shaft 42 moves to the third middle point B4 of the B track, and the second straight line segment 513 is perpendicular to the third straight line segment 521, and the distance from the third middle point B4 of the B track to the first straight line segment 511 is the shortest.

[0115] The second hinge shaft 42 is just a short distance away from the third middle point B4 of the B track, and the first hinge shaft 41 rotates at the first end position A6. The door body 2 continues to rotate to the fifth angle, as shown in FIG. Figure 14 As shown, as the second hinge shaft 42 continues to move, the distance between it and the second straight segment 513 gradually increases. Consequently, due to the force applied to the second hinge shaft 42 by the second groove 52, the first hinge shaft 41 moves away from the first end A6 and slides along the second straight segment 513. When the second hinge shaft 42 moves to the fourth intermediate point B5 of the B track at the largest corner of the first arc segment 512, the first hinge shaft 41 can slide to the third intermediate point A4 of the A track.

[0116] The door body 2 continues to rotate to 90 degrees, as shown in FIG. Figure 15 As shown, when the second hinge shaft 42 continues to move to the second end B6 of the fourth straight segment 523, the first hinge shaft 41 slides from the third midpoint A4 of track A to the fourth midpoint A5 of track A. During this process, due to the force acting on the second hinge shaft 42, it cannot move further at the second end B6, and the first hinge shaft 41 also stops at the fourth midpoint A5 of track A, completing the door opening process.

[0117] For the process of closing the door body 2, the movement state and process of the first hinge shaft 41 and the second hinge shaft 42 are exactly opposite to the door opening process. The opening and closing state of the other three door bodies 2 are consistent with the state and process of the left refrigerated door body 2, which will not be repeated here.
